Written by the creator of Minux, professional programmers will now have the most up-to-date tutorial and reference available today. Revised to address the latest version of MINIX (MINIX 3), this streamlined, simplified new edition remains the only operating systems text to first explain relevant principles, then demonstrate their applications using a Unix-like operating system as a detailed example. It has been especially designed for high reliability, for use in embedded systems, and for ease of teaching.

    This book attempts to capture the engineering wisdom and design philosophy of the UNIX, Linux, and Open Source software development community as it has evolved over the past three decades, and as it is applied today by the most experienced programmers. Eric Raymond offers the next generation of hackers the unique opportunity to learn the connection between UNIX philosophy and practice through careful case studies of the very best UNIX/Linux programs.

    Algorithms have made our lives more efficient, more entertaining, and, sometimes, better informed. At the same time, complex algorithms are increasingly violating the basic rights of individual citizens. Allegedly anonymized datasets routinely leak our most sensitive personal information; statistical models for everything from mortgages to college admissions reflect racial and gender bias. Meanwhile, users manipulate algorithms to "game" search engines, spam filters, online reviewing services, and navigation apps.Understanding and improving the science behind the algorithms that run our lives is rapidly becoming one of the most pressing issues of this century. Traditional fixes, such as laws, regulations and watchdog groups, have proven woefully inadequate. Reporting from the cutting edge of scientific research, The Ethical Algorithm offers a new approach: a set of principled solutions based on the emerging and exciting science of socially aware algorithm design. Michael Kearns and Aaron Roth explain how we can better embed human principles into machine code - without halting the advance of data-driven scientific exploration. Weaving together innovative research with stories of citizens, scientists, and activists on the front lines, The Ethical Algorithm offers a compelling vision for a future, one in which we can better protect humans from the unintended impacts of algorithms while continuing to inspire wondrous advances in technology.

    Expanded and updated for .NET 3.5, this new edition focuses on the design issues that directly affect the programmability of a class library, specifically its publicly accessible APIs. This book can improve the work of any .NET developer producing code that other developers will use. It includes copious annotations to the guidelines by thirty-five prominent architects and practitioners of the .NET Framework, providing a lively discussion of the reasons for the guidelines as well as examples of when to break those guidelines. Microsoft architects Krzysztof Cwalina and Brad Abrams teach framework design from the top down. From their significant combined experience and deep insight, you will learnThe general philosophy and fundamental principles of framework design Naming guidelines for the various parts of a framework Guidelines for the design and extending of types and members of types Issues affecting-and guidelines for ensuring-extensibility How (and how "not") to design exceptions Guidelines for-and examples of-common framework design patternsGuidelines in this book are presented in four major forms: Do, Consider, Avoid, and Do not. These directives help focus attention on practices that should "always" be used, those that should "generally" be used, those that should "rarely" be used, and those that should "never" be used. Every guideline includes a discussion of its applicability, and most include a code example to help illuminate the dialogue. "Framework Design Guidelines, Second Edition, " is the only definitive source of best practices for managed code API development, direct from the architects themselves. A companion DVD includes the Designing .NET Class Libraries video series, instructional presentations by the authors on design guidelines for developing classes and components that extend the .NET Framework. A sample API specification and other useful resources and tools are also included.

    Since the last edition of this book appeared five years ago, there has been a major climate change with regard to web standards. Designers are no longer using (X)HTML as a design tool, but as a means of defining the meaning and structure of content. Cascading Style Sheets are no longer just something interesting to tinker with, but rather a reliable method for handling all matters of presentation, from fonts and colors to the layout of the entire page. In fact, following the standards is now a mandate of professional web design.Our popular reference, Web Design in a Nutshell, is one of the first books to capture this new web landscape with an edition that's been completely rewritten and expanded to reflect the state of the art. In addition to being an authoritative reference for (X)HTML and Cascading Style Sheets, this book also provides an overview of the unique requirements of designing for the Web and gets to the nitty-gritty of JavaScript and DOM Scripting, web graphics optimization, and multimedia production. It is an indispensable tool for web designers and developers of all levels.The third edition covers these contemporary web design topics:Structural layer: HTML 4.01 and XHTML 1.0 (9 chapters), including an alphabetical reference of all elements, attributes and character entities Presentation layer: Ten all-new chapters on Cascading Style Sheets, Level 2.1, including an alphabetical reference of all properties and values. Behavior layer: JavaScript and scripting with the Document Object Model (DOM) Web environment: New web standards, browsers, display devices, accessibility, and internationalization Web graphics optimization: Producing lean and mean GIF, JPEG, PNG, and animated GIFs Multimedia: Web audio, video, Flash, and PDFOrganized so that readers can find answers quickly, Web Design in a Nutshell, Third Edition helps experienced designers come up to speed quickly on standards-based web design, and serves as a quick reference for those already familiar with the new standards and technology. There are many books for web designers, but none that address such a wide variety of topics. Find out why nearly half a million buyers have made this the most popular web design book available.

    Culled from the experience of the Flickr.com lead developer, Building Scalable Web Sites offers techniques for creating fast sites that your visitors will find a pleasure to use. Creating popular sites requires much more than fast hardware with lots of memory and hard drive space. It requires thinking about how to grow over time, how to make the same resources accessible to audiences with different expectations, and how to have a team of developers work on a site without creating new problems for visitors and for each other. Presenting information to visitors from all over the world Integrating email with your web applications Planning hardware purchases and hosting options to have as much as you need without breaking your wallet Partitioning and distributing databases to support large datasets and simultaneous transactions Monitoring your applications to find and clear bottlenecks * Providing services APIs and using services from other providers to increase your site's reach and capabilities Whether you're starting a small web site with hopes of growing big or you already have a large system that needs maintenance, you'll find Building Scalable Web Sites to be a library of ideas for making things work.

    Distinguishing agents (e.g., molecules, cells, animals, and species) from their interactions (e.g., chemical reactions, immune system responses, sexual reproduction, and evolution), Flake argues that it is the computational properties of interactions that account for much of what we think of as beautiful and interesting. From this basic thesis, Flake explores what he considers to be today's four most interesting computational topics: fractals, chaos, complex systems, and adaptation.Each of the book's parts can be read independently, enabling even the casual reader to understand and work with the basic equations and programs. Yet the parts are bound together by the theme of the computer as a laboratory and a metaphor for understanding the universe. The inspired reader will experiment further with the ideas presented to create fractal landscapes, chaotic systems, artificial life forms, genetic algorithms, and artificial neural networks.

    As promoted by enterprises like IBM, Siemens and Cisco Systems, the vision of the "smart city" proposes that this technology can be harnessed by municipal administrators to achieve unprecedented levels of efficiency,security, convenience and sustainability. But a closer look at what this body of ideas actually consists of suggests that such a city will not, and cannot, serve the interests of the people who live in it. In this pamphlet, Everyware author Adam Greenfield explores the ways in which this discourse treats the city as an abstraction, misunderstands (or even undermines) the processes that truly do generate meaning and value — and winds up making many of the same blunders that doomed the High Modernist urban planning of the twentieth century. “Against the smart city” provides an intellectual toolkit for those of us interested in resisting this sterile and unappealing vision, and lays important groundwork for the far more fruitful alternatives to come.
